Answer:

Step-by-step explanation:
+2*k*pi is for the periodicity (if you turn 360° you get back to the same point)
Answer:
77 in ^2 is the best estimate
Step-by-step explanation:
We can get the total area from the sum of the triangle and the semi circle
semicircle
1/2 the area of the semicircle
A = 1/2 pi r^2
1/2 (3.14) ( 4^2)
25.12
Now find the area of the triangle
The base is 16 -r = 16-4 = 12
The height is 8
A = 1/2 bh
= 1/2 (8) (12)
= 48
The total area is 25.12+48 =73.12
Answer:
C
Step-by-step explanation:
to find the first 4 terms, substitute n = 1, 2, 3, 4 into the expression
n = 1 → 1(1 - 1) - 4 = 0 - 4 = - 4
n = 2 → 2(2 - 1) - 4 = 2 - 4 = - 2
n = 3 → 3(3 - 1) - 4 = 6 - 4 = 2
n = 4 → 4(4 - 1) - 4 = 12 - 4 = 8
the first four terms are - 4, - 2, 2, 8 → C
